</p><p>For a <span class="t-spar">reflexpr-operand</span> of form <code><b>(</b></code> <span class="t-spar">expression</span> <code><b>)</b></code>, the <span class="t-spar">expression</span> shall be a (possibly multi-parenthesized) <span class="t-spar">function-call-expression</span> or <span class="t-spar">functional-type-conv-expression</span>.
</p><p>If an unparenthesized operand can be treated as either a <span class="t-spar">type-id</span> or a <span class="t-spar">functional-type-conv-expression</span>, then it is treated as a <span class="t-spar">type-id</span>. Parenthesizes can be used for disambiguation between function-style cast and a <span class="t-spar">type-id</span>. For example, given a class type <code>X</code> with default constructor, <span class="t-c"><span class="mw-geshi cpp source-cpp">reflexpr<span class="br0">(</span>X<span class="br0">(</span><span class="br0">)</span><span class="br0">)</span></span></span> reflects the function type <span class="t-c"><span class="mw-geshi cpp source-cpp">X<span class="br0">(</span><span class="br0">)</span></span></span>, and <span class="t-c"><span class="mw-geshi cpp source-cpp">reflexpr<span class="br0">(</span><span class="br0">(</span>X<span class="br0">(</span><span class="br0">)</span><span class="br0">)</span><span class="br0">)</span></span></span> reflects the expression <span class="t-c"><span class="mw-geshi cpp source-cpp">X<span class="br0">(</span><span class="br0">)</span></span></span>.
</p><p>If the operand designates both an alias and a class name, the type represented by the reflexpr-specifier reflects the alias and satisfies <code>reflect::Alias</code>.
</p><p>If the operand designates a name whose declaration is enclosed in a block scope and the named entity is neither captured nor a function parameter, the program is ill-formed.
</p>
<h4><span class="mw-headline" id="Meta-object_types">Meta-object types</span></h4>
<p>A <i>meta-object type</i> is an unnamed, incomplete namespace-scope class type. A type satisfies the concept <code>reflect::Object</code> if and only if it is a meta-object type. Meta-object types may satisfy other concepts, depending on the operand to <code>reflexpr</code>.
</p><p>It is unspecified whether repeatedly applying <code>reflexpr</code> to the same operand yields the same type or a different type. If a meta-object type reflects an incomplete class type, certain type transformations cannot be applied.
</p><p>A meta-object type allows inspection of some properties of the operand to <code>reflexpr</code> through type traits or type transformations on it.
